Hello,
By default, when firing up a new compute instance with Oracle Linux, two volumes are created : "boot" (effectively root) and "oled" (/var/oled).
From my understanding, this "oled" partition serve to store kernel crash logs.
As I find it excessive to keep 10Gb for that, I would like to make it lower, but since this is two completely separate encrypted volumes, I figured out it may be possible to achieve lower size for this volume using cloud-init script when firing the compute instance in the first place.
Problem is, I don't know where to start, reading cloud-init documentation did not help me there.

When a compute instance has finished it's provisioning, the useable space is in /dev/mapper, and cloud init doesn't support that.
